I'm having difficulty finding the bug

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            try
            {

                Console.Write("Enter the number of times to print \"Yay!\": ");
                string input = Console.ReadLine();

                int count = int.Parse(input);

                if count > 0
                    {
                        int i = 0;
                        while(i < count)
                        {
                            i += 1;   
                            Console.WriteLine("Yay!");
                        }
                    }
                else
                {
                    Console.WriteLine("You must enter a positive number");
                }
            }    
            catch(FormatException)
            {
                Console.Write("You must enter a whole number");
            }
        }
    }
}
